Many refrigerators have automatic ice makers that produce a full canister of ice. When power goes out, collect water from melted ice-it’s safe to drink.
Another source of water during an emergency is toilet reservoir tank.
NOT the toilet bowl (which is dirty), but the reservoir inside the unit behind you when you sit down,which contains clean water that can be used. Make sure the toilet tank does no contain a cleaning agent such bleach, ammonia, or a bowl-cleaner cake. If you feel doubtful about drinking toilet water, use it for washing or sanitation- or distill it before drinking as a last resort. (I will discuss distilling water in a later BLOG)
Pool or Hot Tub
Pool or hot-tub water should not be used for drinking but can be used for washing and sanitation needs. The only way to purify pool water so it’s safe for drinking is to distill it. Distillation is achieved by boiling water to produce water vapor, which leaves most contaminants behind and turns back into water that is safe for drinking.
